There are rumors that Sony is going to reveal Syphon Filter 4 at E3. The PS3 game will be a follow up to the Logan's Shadow PSP title.

There are forum reports that there was a page on Sony's community site – which has now been taken down – detailing that the stealth game would be coming to the PS3 at the end of next year.

We'll have to wait until next week to possibly find out more.
